A Life Course Approach For Injury Prevention

The Hosking and colleagues 2011 article “A life course approach to injury prevention: a “lens and telescope” conceptual model” examines the prospect of extending common injury concepts (Haddon Matrix) by integrating ecological (lens) and life course (telescope) models into injury research. The paper delineates how the “lens and telescope” models would urge looking beyond proximal influences to injury to more distal, but equally important potential contributing factors. Given the main tenets of life course and ecological theories are time and context, an injury would not merely be considered as an incident influenced by distinct events. Rather, the injury would be as a result of a lifetime (and previous lifetimes) of contributing factors. For example, an injury caused by a car accident is not merely influenced by speed, but by behavior modeling and the individual’s access to resources based upon socio economic status. According to Hosking, previous injury prevention concepts were narrow in their focus, only focusing on the “host,” “vehicle” or “environment.” By integrating life course and ecological theories the scope is expanded through the theories core principles. The following is a brief outline of the core principles of life course and ecological theory respectively. Life Course Approach Dr. Glen Elder, the major contributor to the life course approach, developed the core principles of the theory after analyzing the data from his “Children of the Great Depression”
